COLD WEATHER NOT just causes cough and flu, but also affects the skin.

Dr DM Mahajan, senior consultant, dermatology, Indraprastha Apollo Hospitals, says: “Cold weather affects the skin mainly because low temperatures reduce blood flow to the skin surface. When it is cold, the body tries to conserve heat by narrowing blood vessels, especially in the hands, feet, ears and nose. This reduced circulation means less oxygen and nutrients reach the skin, making it more sensitive and prone to damage. Cold air also holds very little moisture, which dries out the skin and weakens its natural protective barrier. In conditions like chilblains, repeated exposure to cold followed by sudden warming causes inflammation in small blood vessels, leading to redness, swelling and itching.

Cold urticaria happens when the skin reacts abnormally to cold, releasing chemicals like histamine, which cause hives, itching or swelling. People with sensitive skin, poor circulation, anaemia or those who stay outdoors for long periods are more likely to experience these problems during winter”
